中文摘要: 由于芯片制造系统规模大、造价高,工艺复杂、制造周期长,以及多重入的生产流程,造成了动态多瓶颈现象,使得其调度问题非常复杂。虽然多瓶颈多重入特征使得调度问题更为复杂,但另一方面也为有效地解决调度问题提供了契机。本项目从该特征入手,研究以半导体芯片制造为典型代表的大规模复杂制造的生产调度方法。整个研究思路分为瓶颈辨别、调度问题分解和调度求解三步:首先分析具有多重入生产流程的生产系统中动态多瓶颈产生的原因,以及多瓶颈辨识和区分方法;其次在此基础上提出基于多瓶颈多重入特性的调度问题分解方法;最后考虑到调度规则的快速有效性和智能算法在求解精度方面的优势,拟研究基于多种规则和智能算法的混合调度方法,并通过序优化和响应曲面法等优化方法获得有效的算法组合方案和相关参数。本项目力图探索出一套能够有效解决半导体芯片制造系统复杂生产调度问题的科学方法,以期能提高我国半导体晶圆制造企业的生产控制水平。

英文摘要: Due to the large number of equipment, high investment cost, complex process, long cycle time, multi-bottlenecks and multiple re-entrant process flows, the scheduling of semiconductor wafer fabrication is very complex. However, the multi-bottlenecks and multiple re-entrant flows also provide a chance to solve the scheduling problem efficiently. In this project, we will study the scheduling method in large scale complex manufacturing system,such as semiconductor wafer fabrication. First, this project will analyze the factors in multi-bottlenecks and the characters of the bottlenecks in a dynamic system with multiple re-entrant process flows. Then the multi-bottlenecks detection and identification methods will be introduced. We will try to decompose the large scale complex scheduling problem according to the multi-bottlenecks and multiple re-entrant flows. And then the hybrid scheduling methods including different rules and intelligent algorithms will be developed to solve the decomposed sub-problems. Finally, simulation based methods such as ordinal optimization theory and response surface methodology will be adopted to select appropriate rule combination and optimize the combination parameters. The project is of considerable significance to improve the performance of the semiconductor wafer fabrication company in
